STUDY OF THE NUCLEAR POWER PLANT CONTAINMENT DAMAGE CAUSED BY IMPACT OF A PLANE

Abstract eng:
The article is a contribution to the discussion concerning nuclear safety which has intensified after the Fukushima Daiichi nuclear disaster. The parametric study presented here is focused on the containment damage evaluation for various materials, containment wall thicknesses and different aircraft speeds before impact. A detailed analysis of plane impact is also included. The solution was obtained by the explicit finite element method utilizing the RFEM program. The knowledge gained from this study might also be applied to the detailed impact analysis of a plane on other particular nuclear power plant containment structures as needed. The purpose of this study was also to foster experiential suggestions for improving the explicit method in the RFEM program in order to release it for RFEM users.
